IMPROVEMENT IN lWlhllll0llll`SASII SUPPORTERS.

TO ALL WHOM IT MAY OONCERN:

Be it known that I, RICHARD VOSE, of the city, county, and State of New York, have invented a new and usefullmprovement in Window-Catches; and I do hereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings forming a part of this specication, in

which- 4 i Figure 1 is a front view in perspective of a window-sash and frame provided with my improved catch.

.Figure 2,:1. rear 'elevation of the same with the wood-work broken away, illustrating theposit'ion and arrangement of the-several parts of my catch.

Figure 3, said parts detached from sash and frame, showing the same inore clearly.

Similarv letterindicate like parts in all ofthe figures. l

-The nature of-myimprovement consists in the use of a simple crank, projecting at right angles from a thumbpie'ce, and connected by a Wire to a suitable window-catch, so as to release or withdraw the same from a rack placed i-n the frame of a window also in the use-'of an upright catch, acting as a hook, by which the window shall hang Ifrom the rack when raised instead of being propped up thereby, as in the ordinary forms; and finally, in the combination of a pin immediately with-the catch to withdraw the same, independent of the lever or other devices foi-.the purpose.. In the accompanying drawings- 'A represents' the crank or radial arm, projecting from a pin in the centre of a Asuitable thumb-piece,

lat right angles to the thumb-piece, said pin serving as apivot, upon which the crank may rock or vibrate.

The crankgA, pivot ci, and thumbpiece b, may al1 be cast or formed in one. The pivot a of the crank is embraced between the two parts of a divided circular front plate C, which are each recessed properly to embrace one-half of its perimeter, and when united form a journal-box therefor. The plate C serves thus not only to support the pivot ofthe crank A, bntwhen secured in place upon the sash covers the recess cut out therein, in which the crank vibrates, and conceals the same from sight, leaving only the thimb-piece b in view. The catch which serves andl acts to support the window-sash when raised, consists of a hook, e, secured upon the upper free end of a spring, j', whose lower end is attached to the lower edge of the sash,.solas.to'project upwardly in a slot formed in the side edge of said sash, as seen in fig. 2 of the drawings.4 A rack, It, is placed in the window-frame, and the tendency of thespringfis to keep the'attached hook e pressed against this rack, unless forcibly withdrawn therefrom. The upper end of the springfis connected by a. wire or chain, m, tothe crank A, so that by turning the'thumb-'piece b, and thus moving said crank, the spring with itsattached catch will be withdrawn as required. The connecting wire passes through a simple hole, drilled from the slot in which the catch works, to the recess in which the crank vibrates. A pin, r, is secured to the hook e of the catch, to project slightly through a simple slot on' the inner side of the sash, whereby, if the wire or crank breaks or become dsarranged, the catch may be withdrawn 'independently thereof.

My improved catch, and devices for operating the same, may be manufactured at much less cost than any now in use, the whole being embraced in a face plate, C, in two simple pieces; a crank and its thumb-piece in one piece, a spring and attached hook, and a piece of wire to connect the crank and spring. The spring s fastened directly to the sash without the extra-expense of a hingedjoin't and a separate catch-piece, as is found in the usual forms of devices of this'character, in which the' catch swings from above and props up the window instead of holding it up as in this case.

Havingv thus fully described my improvements, what I claim therein as new, and-desire to secure by Letters Patent, is y y .1'. A thumb-piece and crank, united to form one piece, when supported by a simple divided plate, C, upon a window-sash, and combined with a spring catch uponthc edge or side of said sash by means of a connectingcord or wire, all substantially in the manner and for the purpose herein set forth.

2. I claim also the coinbinationof `a pin, r, with a spring-catch, e, as herein described, when saidpin is made to project in or through a slot cut in the sash, all substantially as and furthe purpose herein set forth.

The foregoing specification of my improvements in window-catches signed by rnc this day of April. A. D.
